Brainrot: Memory & Brain Games

Your attention isn't broken — it's just out of practice. This is the gym for it. Brainrot is a focused N-Back trainer — brain games for memory and concentration, built on the most studied working memory task in cognitive science. No feeds, no ads, no dopamine slot machine — just you and the rep that rebuilds your concentration. HOW IT WORKS You watch a stream of stimuli and respond when the current one matches what appeared N steps earlier. In 2-back, you match the item from two steps ago. Simple to learn, genuinely demanding to hold — and that gap is where working memory gets trained. ONE TASK, ENDLESS DEPTH • Single, Dual, Triple, and Quad N-Back (1 to 4 streams at once) • Stimuli: numbers, letters, sounds, shapes, colors, grid cell position • 1x3 and 3x3 grid patterns • Mix visual and audio streams freely — 150+ combinations • Adaptive N-level that raises and lowers difficulty according to rules you customize • Two separate audio streams at once, one per ear — put your headphones on for a true dual-sound challenge NOW ON MAC — AND BUILT FOR THE KEYBOARD • Runs on Mac, iPad, and iPhone — train on the big screen at your desk • Full hardware-keyboard play: press Space to start or stop, and H / J / K / L to answer each stream • A built-in Keyboard Shortcuts guide keeps every key one glance away • Ideal for fast, heads-down Quad sessions — hands on the keys, eyes on the streams TRACK REAL PROGRESS • Per-stream scoring: correct, missed, incorrect • Instant feedback on wrong taps, with optional haptics • Session results after every round • Daily goals to keep the habit • Full training history BUILT TO RESPECT YOUR FOCUS • With Premium, train fully offline • Zero ads.

We don't promise IQ points or medical outcomes. It's a serious, well-built tool — the results come from showing up and doing the reps. Put the phone to work for once. Start with Single N-Back, then build toward Quad at your pace. Missing a feature? Write to me from Settings in the app. Focus is a skill. Train it.
